# service xencommons status
test: -z: unexpected operator
xenstored is running as pid 1090.
xenconsoled is not running.

Arises from these conditionals -- first one is fine, second one is not:

	if test -n "$xenconsoled_pid" -a -n "$xenstored_pid";
	then
		echo "xencommons are running as pids $pids."
		return 0
	fi
	if test -a -z "$xenconsoled_pid" -a -z "$xenstored_pid";
	then
		echo "xencommons are not running."
		return 0
	fi

>How-To-Repeat:
service xencommons status
>Fix:
change `test -a -z ...' to `test -z ...'
